Example

Executing the example requires that the repository contains a table with the TABLE_L identifier.

Add links to the Metabase, Db system assemblies.

Sub UserProc;
Var
    mb: IMetabase;
    Table: ITable;
    FKeys: ITableForeignKeys;
    Key: ITableForeignKey;
Begin
    mb := MetabaseClass.Active;
    Table := mb.ItemById("TABLE_L").Bind As ITable;
    FKeys := Table.ForeignKeys;
    If FKeys.Count > 0 Then
        Key := FKeys.FindById("FK");
        If Key <> Null Then
            Debug.WriteLine(Key.Name);
        End If;
    End If;
End Sub UserProc;

After executing the example the external key with the FK identifier is searched for in the TABLE_L table. If the key is found, its name is displayed in the console window.
